Hear is a idea for you to try out. There are many ways to do the typoligy for noses.

put the edges along the green lines.. the face with the green dot is facing out to the side. the one with the red angeled in. this creates that skin in the back of the nostral flare.

the red ? mark is for when you get your mouth in there you might not want your edges to run like that.

A wire on this one would be a little more clear as to what you have.

cool start.
